Model predictions and experimental results for the rotordynamic characteristics of leakage flows in centrifugal pumps [PDF]
The role played by fluid forces in determining the rotordynamic stability and characteristics of a centrifugal pump is gaining increasing attention. The present research investigates the contributions to the rotordynamic forces from the discharge-to ...

Effect of swirl on fluctuation of pressure drop in a gas–liquid slug flow
Slug flow as one of the typical two-phase flow patterns occurs widely in industry. The fluctuating phenomenon in slug flow is harmful to the pipeline system and should be suppressed.

Combustion in swirling flows: A review
Melting and burning of suspended alkane droplets are studied experimentally under electric field. It is found that the melting rate substantially decreases if electric field strength exceeds some critical value. It is about 60 kV/m under our experimental conditions.
